Ehrenfried Pfeiffer lays out the essential practices for successfully operating a biodynamic farm, including the principles behind each technique and practice. He backs up these methods with scientific research and data, as well as his own experience as a farmer and researcher, describing what works and what doesn't. Pfeiffer covers soil qualities, making compost, crop rotation, best planting practices, using biodynamic preparations and sprays, and much more--all with the goal of growing the highest-quality foods by using sustainable methods and working with nature and caring for the earth.Bio-Dynamic Gardening and Farming (Vol. 2) includes: FIELD AND LABORATORY TRIALS AND RESULTSMINERAL RELATIONSHIPS BETWEEN SOILS AND PLANTSPLANTS ABSORB ORGANIC SUBSTANCES FROM SOILTHE BIOLOGICAL BALANCEHEALTHY AND DISEASED PASTURESBALANCED NUTRITION OF SOILS AND PLANTSSOIL BUILDING VERSUS NUTRIENT SOLUTIONSOILS AND ACTIVATORS AND THE NITROGEN PROBLEMAVAILABILITY OF NITROGEN PHOSPHATE AND POTASH IN SOILS DUE TO APPLICATION OF MICROORGANISMSSEVEN YEARS OF SOIL SURVEY ON A BIO-DYNAMIC FARMMICROLIFE AND MICROCHEMISTRY IN SOILSAVAILABLE, WATER-SOLUBLE OR STORAGE: Humus Decides The IssueFERMENTATION VERSUS PUTREFACTION AND DECAYCOMPARATIVE SOIL TESTS 1951-1961 OF A BIO-DYNAMIC FARM
